Every day on eBay, millions of people buy and sell a vast array of goods, from rare collectibles and antiques to used cars and celebrity memorabilia. The internet auction site is remarkably easy to use, which accounts in part for its huge popularity. But how does eBay really work, and how does it compare to other kinds of auctions? These are questions that led Ken Steiglitz--computer scientist, collector of ancient coins, and a regular eBay user--to examine the site through the revealing lens of auction theory. The result is this book, in which Steiglitz shows us how human behaviors in open markets like eBay can be substantially more complex than those predicted by standard economic theory. In these pages we meet the sniper who outbids you in an auction's closing seconds, the early bidder who treats eBay as if it were an old-fashioned outcry auction, the shill who bids in league with the seller to artificially inflate the price--and other characters as well. Steiglitz guides readers through the fascinating history of auctions, how they functioned in the past and how they work today in online venues like eBay. Drawing on cutting-edge economics as well as his own stories from eBay, he reveals practical auction strategies and introduces readers to the fundamentals of auction theory and the mathematics behind eBay. Complete with exercises and a detailed appendix, this book is a must for sophisticated users of online auctions, and essential reading for students seeking an accessible introduction to the study of auction theory.

This paper evaluates the importance of auction format on bidding behavior and seller revenue, focusing on differences in performance under uniform-price and discriminatory-price formats. The analysis is based on a standard benchmark model from which empirically-testable hypotheses are derived on the optimal amount of bid shading that generates revenue equivalence between the two formats. Applying this model to data from the IMF gold auctions run in 1976-80, we find evidence of statistically significant shading in excess of the theoretically-derived optimum under the discriminatory format. This evidence suggests greater seller revenue under the uniform-price format.

In this dissertation I study bidding behavior in Internet Auction Markets. I focus on practice called"multiple bidding" which occurs when a single bidder places numerous bids throughout the same auction. Multiple bidding appears frequently in the data but the incentives that motivate it are not well understood. In the first chapter I develop a theoretical model in which multiple bidding is an equilibrium behavior by rational bidders. The model has a dynamic auction with two bidders who can search for outside prices while bidding in the auction. Each bidder has a search cost which is her private information. When outside prices are private (independently drawn and identically distributed), then, there is an equilibrium in which bidders with the lower search costs bid only late and always search, while the bidders with higher search costs bid both early and late and search as if they coordinated their search decisions, i.e., the bidder with the lower search cost searches and the other bidder does not. This equilibrium by itself provides an explanation of two frequently occurring bidding patterns (late and multiple bidding). In the second chapter I study experimentally the effect of early bids in dynamic auctions on how bidders search for outside prices. The design has two bidders participating in an ascending clock-auction during which any one of the bidders can pause the auction clock. This I interpret as placing an early bid. Once the auction is paused both bidders can simultaneously search for an alternative outside price. Results indicate that pausing decisions by subjects impact their subsequent searching for outside prices, i.e., whether a subject decides to search or not depends on whether she has paused the auction or not. Subjects behave as if they coordinated their searching decisions: the bidder who pauses the auction also searches with high frequency and the other bidder does not. Because this type of behavior increases both the efficiency and the profitability of the auction we favor the use of policies that promote early bidding inpractice, such as, longer auctions and lower public reserve prices.

An invaluable account of how auctions work—and how to make them work Few forms of market exchange intrigue economists as do auctions, whose theoretical and practical implications are enormous. John Kagel and Dan Levin, complementing their own distinguished research with papers written with other specialists, provide a new focus on common value auctions and the "winner's curse." In such auctions the value of each item is about the same to all bidders, but different bidders have different information about the underlying value. Virtually all auctions have a common value element; among the burgeoning modern-day examples are those organized by Internet companies such as eBay. Winners end up cursing when they realize that they won because their estimates were overly optimistic, which led them to bid too much and lose money as a result. The authors first unveil a fresh survey of experimental data on the winner's curse. Melding theory with the econometric analysis of field data, they assess the design of government auctions, such as the spectrum rights (air wave) auctions that continue to be conducted around the world. The remaining chapters gauge the impact on sellers' revenue of the type of auction used and of inside information, show how bidders learn to avoid the winner's curse, and present comparisons of sophisticated bidders with college sophomores, the usual guinea pigs used in laboratory experiments. Appendixes refine theoretical arguments and, in some cases, present entirely new data. This book is an invaluable, impeccably up-to-date resource on how auctions work--and how to make them work.

Abstract: Standard literature on auctions considers isolated markets with bidders that are ex ante identical and independent. My dissertation research considers the behavior of bidders and sellers when they take into account other auctions and bidders' relative roles outside of a given auction. I further extend this investigation through classroom experiments. In the first chapter, I study bidders' optimal strategies under negative externalities (i.e., the auction may incur losses (instead of zero payoffs) to the losing bidders). I construct a model of auction with three bidders. One bidder is special in the sense that if he wins, both of the other bidders will incur a loss; the other two bidders are regular in the sense that as in a traditional auction, if one of them wins, the losing bidders will receive zero payoffs. Intuitively one expects regular bidders to bid more aggressively than normal to avoid the loss. However, I find that in an ascending clock auction, in equilibrium regular bidders bid less aggressively and quit before reaching their private values. This occurs because a regular bidder may have to bid above his value in order to win against the special bidder and thus risks negative profit by bidding aggressively. Since both regular bidders avoid the externality if either wins, there is a free riding incentive. Despite free riding, in most cases the clock auction is ex post efficient However, in first-price sealed bid auctions free riding and aggressive bidding incentives are simultaneous, so ex post efficiency is less frequent. I also conducted classroom experiments which suggest that bidders more often exhibit aggressive bidding rather than free riding in an ascending clock auction; furthermore, I show that in first-price sealed bid auctions, regular bidders bid more aggressively than the special bidder, indicating aggressive bidding incentives dominate free riding incentives. In the second chapter, I construct an auction model in which both number of bidders and sellers' reserve prices are endogenously determined, and estimate the value distribution among eBay bidders. I assume each bidder has a choice of auctions with different reserve prices and other auction specific factors (seller's reputation, shipping cost, auction duration, etc.). I show that in equilibrium, 1) each bidder must be indifferent to entry in any auction, and 2) each seller's reserve price must maximize expected revenue given auction structure and bidder entry behavior, which jointly determines the equilibrium number of bidders in each auction. Few theoretical works have been done to find the positive optimal reserve price when the number of bidder is endogenous. And previous empirical work usually uses observed bids to estimate bidders' value distribution and take sellers' choice (e.g., reserve prices) as exogenous. Based on the equilibrium relationship described above, my model allows estimation of bidders' value distribution not only from observed bids, but also from the number of bidders and reserve prices. To apply this structural estimation method, I use eBay digital camera auction data to estimate bidders' value distribution from bid observations and reserve prices.

This research examines bidding behavior in a sealed bid first price multi-attribute auction environment. The auction environment is designed to allow subjects to bid on multiple attributes, where an attribute is analogous to a component of a compensation package. Preliminary findings in base case experiments reveal that over successive rounds bids converge to subject's reserve price, independent of the number of sellers in a market.
